Is Blockchain Security Required Only by Finance Sector?

Is blockchain security required only by the banking and finance sector? There is no doubt that the blockchain technology is still in its nascent stage but in spite of that this technology offers adequate security to make domestic and cross-border payments safely and quickly.

As a result, several industries related with cryptocurrencies are widely using this technology to move their transaction and payment needs to blockchain.

However, blockchain security is not only needed by the companies related to payments such as the banks and financial institutions.

In fact, its need and implementation is not restricted to banking and financial sectors.

Blockchain security and technology is extremely versatile. It is not only used to maintain the records of the financial transactions but also for several other things such as:

  • Storing medical records
  • Storing concluding binding agreements
  • Storing personal credit records
  • Tracking the flow of goods in transit
  • Tracking the provenance of artwork
  • Verifying payments through a supply chain and more.

Therefore, blockchain technology, which initially started as the underlying technology to make Bitcoin transactions almost a decade back, now has grown and become one of the most significant and promising technologies for extenuating cyber security.

In this digital age where data breaches and hacks are common and continue to plague the organizations all over the world, blockchain security is essential.

This enables a lot of different companies to safeguard their data and operations and in the process save a lot of money by preventing them from incurring heavy losses in business.

If you are thinking on the lines of implementing blockchain security in your business, you should first know about the technology to leverage blockchain security.

This article will help you a great deal in that respect.

Is Blockchain Security Required Only by the Banking and Finance Sector

Inadequate cyber security will not only affect the banking and finance industry but could also impact others such as law enforcement, accounts, healthcare, and a lot of other sectors.

In short, the future of blockchain is near when it comes to cyber security.

Blockchain technology is a virtual ledger or Digital Ledger Technology that has the ability to verify and record a high volume of digital transactions quickly, efficiently, and safely.

All transaction data is maintained in a verifiable and transparent register.

There is no need for any central supervision for it to operate since it is decentralized.

Each block of data is connected with the previous one in the chain with a hash after proper verification and validation by all the participants on the chain.

Once it is added to the chain, the records are immutable since these are secured with digital signatures and encryption.

Any forced changes made in one block will need changing all preceding and subsequent blocks along with it.

This makes it resistant to fraud and hacks to a great extent. It also eliminates the chances of performing any fraudulent activity on the chain such as duplication of transactional records.

This is what is wanted when companies transfer funds or receive payments and that is why blockchain is spreading across a wide range of industries.

Its use cases seem to be endless as it is, but now, with the influx of the metaverse, the significance of the blockchain technology will be even more.

In short, blockchain technology allows purchasing crypto coins, Non-Fungible Tokens and also adds value storage.

It offers greater veracity to the digital information ecosystem.

Future of Blockchain Security

Looking back at a decade from now, blockchain started its journey simply being a supporting technology for Bitcoin, a disruptive product.

But now, in just over ten years’ time the use and popularity of blockchain has expanded unimaginably and has grown into a promising technology to ensure cyber security.

In this digital age, all data and info are stored online and are shared among known and unknown people through the internet.

This is the case for all businesses and organizations and therefore they all need to depend on different digital means.

Therefore, industries are on the lookout for new technologies to improve network security and data privacy and as of now blockchain security seems to be leading the way.

Now with blockchain technology they can conduct transactions and at the same time record the transaction history easily and safely which will be immutable.

This has enabled them to ensure that the primary and vital needs of reliability and data security are met.

Now the businesses do not have to rely on cloud storage technology that is also evolving continuously to transfer data online with a constant fear of security protocols being lapsed.

Therefore, with a more transparent and decentralized blockchain security, there is no risk of data and sensitive information being exposed to the malicious actors anymore.

In addition to that, there are also a few other specific benefits offered by blockchain security.

It offers a decentralization storage system in which data is stored across several computers participating on the chain which does not give the hackers an easy access to the system as a centralized storage system.

In fact, they have to attack or compromise the entire system which makes it quite a complex and cumbersome process.

Blockchain security also protects the IoT or edge devices such as mobile phones, routers, cameras, and switches which also offer an entry point to the hackers, if compromised.

These connected devices of the system can make their own security decisions because the blockchain technology analyzes the network and forms a consensus to ensure that there are no suspicious activities on the chain.

Therefore, each of these devices acts as another additional hurdle for the hacker that they need to overcome to get into the system.

Messaging communication is also secured by blockchain security.

Today, messages are sent by businesses through multiple digital channels and use different formats for it.

This has improved flexibility in collaboration and production but also has increased the risks in it.

Blockchain technology offers the benefits of E2EE or End-To-End Encryption that encrypts information that prevent anyone else apart from those engaged in the communication from reading the messages.

This means that the app developer, internet service providers, and even the government cannot read the messages.

With all these benefits offered by blockchain security, its future is quite secure and is not going to go anywhere sooner or later.
